Apple is nuts - Video compression via JPG/JSON/canvas

One of my coworkers sent me this today. I did a search and didn't see it posted, so I figured I'd share. I'm not a developer by trade and my JS knowledge is limited, but I understand most of what's going on. Pretty awesome IMO.

awesome? it is a problem that any decent engineer /developer would be able to solve in a similar manner.

*shrug* I'm not a developer or engineer, so it seemed pretty cool to me. Guess I'm easily amused.

Yeah, nothing found here that's really all that interesting other than the fact that the iphone can only display video tags at fullscreen. More like apple fails...

As someone who works for a digital media company working on mobile development on android/ios, I can tell you that android video tag is no saint.

Never said it was...I only picked up android a few days ago and have little to no experience.

I suspect that you got sidetracked by the retina display thing.

This is cooler than that.

What exactly is a MPEG other than the 3 frame types (I, P, B) where you end up taking one I frame and then using the P and B frames as often as you can and the I frames as little as possible. What Apple did is basically took a limitation of their platform - not being able to use the video tag in a non-fullscreen way - and hacked together a rather inefficient and costly (processing wise) solution. A neat read through in terms of the math involved and the work they did - but not revolutionary...nor commendable.

Limitation of Mobile WebKit, not the iOS platform, Android suffers the same limitations.

It's neat. That's what it is.

Strangely, the iPad seems to do embedded video just fine in iOS 6. I watched a clip on redlettermedia.com last night and it plays in the page with a full-screen option.
